Definitions
- the present invention relates to a pharmaceutical composition
- a pharmaceutical composition comprising a migration factor that induces pluripotent stem cells to a damaged site.
- Non-patent Document 1 a cell having differentiation potential obtained from an adult, for example, a bone marrow mesenchymal cell fraction (MSC) having differentiation potential into bone, cartilage, adipocyte, nerve cell, skeletal muscle and the like (Non-patent Documents 1 and 2)
- MSC bone marrow mesenchymal cell fraction
- iPS cells Patent Document 1 have been reported as adult-derived pluripotent stem cells. For the establishment of iPS cells, a specific gene or a specific gene is identified in a fraction of mesenchymal dermal fibroblasts. In addition to requiring a very complicated operation of introducing the above compound into somatic cells, iPS cells have a high tumorigenic ability, and therefore there is an extremely high hurdle for clinical application.
- SSEA-3 Stage-Specific Embryonic Antigen-3
- Muse cells Pluripotent stem cells (Multilineage-differentiating Stress Enduring cells; Muse cells) are responsible for the pluripotency of the mesenchymal cell fraction and can be applied to disease treatments aimed at tissue regeneration (Patent Document 2; Non-Patent Document 3; Non-Patent Document 4).
- Non-patent Document 2 pluripotent stem cells
- Non-patent Document 3 the mechanism by which Muse cells are induced in damaged tissues is not elucidated, and migratory factors that induce Muse cells to the site of injury have not been identified.
- An object of the present invention is to provide a medical use using pluripotent stem cells (Muse cells) in regenerative medicine, to enhance the migratory activity of Muse cells, and to efficiently accumulate Muse cells at the damaged site. It is an object of the present invention to identify a migratory factor for providing a pharmaceutical composition containing the migratory factor.
- Muse cells pluripotent stem cells
- the present inventors have succeeded in identifying a migratory factor that induces Muse cells to the damaged site by making full use of proteome analysis, and sphingosine-1-phosphate (S1P) is one of the migratory factors.
- S1P sphingosine-1-phosphate
- Enhancing the activity of migrating includes initiating the migration of Muse cells present in mesenchymal tissue to the damaged site.
- a pharmaceutical composition for activating pluripotent stem cell migration comprising a compound that activates sphingosine-1-phosphate receptor 2 as an active ingredient.
- the compound that activates sphingosine-1-phosphate receptor 2 is an agonist of sphingosine-1-phosphate receptor 2.
- the sphingosine-1-phosphate receptor 2 agonist is sphingosine-1-phosphate or a derivative thereof.
- An agonist of sphingosine-1-phosphate receptor 2 is 1- (2- (1-benzyl-2,5-dimethyl-1H-pyrrol-3-yl) -2-oxoethyl) -5- (tri Fluoromethyl) pyridin-2 (1H) -one, 1- (2- (1-benzyl-2,5-dimethyl-1H-pyrrol-3-yl) -2-oxoethyl) pyrrolidine-2,5-dione, -(2- (1-benzyl-2,5-dimethyl-1H-pyrrol-3-yl) -2-oxoethyl) -3-methylimidazolidine-2,4,5-trione, 1- (1-benzyl- 2,5-dimethyl-1H-pyrrol-3-yl) -2-((1-methyl-1H-tetrazol-5-yl) thio) ethanone and (S) -1- (2- (1-benzyl- 2,5-dimethyl-1H-pyrrol-3

本発明の遊走因子によって損傷部位に誘導される多能性幹細胞は、本発明者らの一人である出澤が、ヒト生体内にその存在を見出し、「Muse(Multilineage-differentiating Stress Enduring)細胞」と命名した細胞である。Muse細胞は、骨髄液や真皮結合組織等の皮膚組織から得ることができ、各臓器の結合組織にも散在する。また、この細胞は、多能性幹細胞と間葉系幹細胞の両方の性質を有する細胞であり、例えば、それぞれの細胞表面マーカーである「SSEA-3(Stage-specific embryonic antigen-3)」と「CD105」のダブル陽性として同定される。したがって、Muse細胞又はMuse細胞を含む細胞集団は、例えば、これらの抗原マーカーを指標として生体組織から分離することができる。Muse細胞の分離法、同定法、及び特徴などの詳細は、国際公開第WO2011/007900号に開示されている。また、Wakaoら(2011、上述)によって報告されているように、骨髄、皮膚などから間葉系細胞を培養し、それをMuse細胞の母集団として用いる場合、SSEA-3陽性細胞の全てがCD105陽性細胞であることが分かっている。したがって、本発明における医薬組成物においては、生体の間葉系組織又は培養間葉系幹細胞からMuse細胞を分離する場合は、単にSSEA-3を抗原マーカーとしてMuse細胞を精製し、使用することができる。なお、本明細書においては、SSEA-3を抗原マーカーとして、生体の間葉系組織又は培養間葉系組織から分離された多能性幹細胞(Muse細胞)又はMuse細胞を含む細胞集団を単に「SSEA-3陽性細胞」と記載することがある。また、本明細書においては、「非Muse細胞」とは、生体の間葉系組織又は培養間葉系組織に含まれる細胞であって、「SSEA-3陽性細胞」以外の細胞を指す。
(i)テロメラーゼ活性が低いか又は無い;
(ii)三胚葉のいずれの胚葉の細胞に分化する能力を持つ;
(iii)腫瘍性増殖を示さない;及び
(iv)セルフリニューアル能を持つ
からなる群から選択される少なくとも1つの性質を有してもよい。本発明の一局面では、本発明において対象とされるMuse細胞は、上記性質を全て有する。ここで、上記(i)について、「テロメラーゼ活性が低いか又は無い」とは、例えば、TRAPEZE XL telomerase detection kit(Millipore社)を用いてテロメラーゼ活性を検出した場合に、低いか又は検出できないことをいう。テロメラーゼ活性が「低い」とは、例えば、体細胞であるヒト線維芽細胞と同程度のテロメラーゼ活性を有しているか、又はHela細胞に比べて1/5以下、好ましくは1/10以下のテロメラーゼ活性を有していることをいう。上記(ii)について、Muse細胞は、in vitro及びin vivoにおいて、三胚葉(内胚葉系、中胚葉系、及び外胚葉系)に分化する能力を有し、例えば、in vitroで誘導培養することにより、肝細胞、神経細胞、骨格筋細胞、平滑筋細胞、骨細胞、脂肪細胞等に分化し得る。また、in vivoで精巣に移植した場合にも三胚葉に分化する能力を示す場合がある。さらに、静注により生体に移植することで損傷を受けた臓器(心臓、皮膚、脊髄、肝、筋肉等)に遊走及び生着し、分化する能力を有する。上記(iii)について、Muse細胞は、浮遊培養では増殖速度約1.3日で増殖するが、10日間程度で増殖が止まるという性質を有し、さらに精巣に移植した場合、少なくとも半年間は癌化しないという性質を有する。また、上記(iv)について、Muse細胞は、セルフリニューアル(自己複製)能を有する。ここで、「セルフリニューアル」とは、1個のMuse細胞を浮遊培養することにより得られる胚様体様細胞塊に含まれる細胞を培養し、再度胚様体様細胞塊を形成させることをいう。セルフリニューアルは1回又は複数回のサイクルを繰り返せばよい。
これまで、Muse細胞は成体に投与されると損傷部位にホーミングし、一方、非Muse細胞は損傷部位にホーミングしないことが知られているが、Muse細胞を損傷部位に誘導する遊走因子は知られていない。そこで、損傷部位にMuse細胞を誘導する遊走因子が存在すると仮定した場合、最初に、Muse細胞に特異的に発現しているが、非Muse細胞には発現していないタンパク質(特に、受容体)を特定することにより、それに対するリガンドなどが遊走因子である可能性が高いと考えられる。
上記で同定されたMuse細胞に特異的に発現しているタンパク質のうち、例えば、遊走因子の受容体となり得るものを選択し、これらの受容体に対するリガンドが遊走因子となり得るかどうかを検討することによって、Muse細胞の遊走因子を特定することができる。一般に、細胞の遊走を測定する方法としては、限定されないが、in vitroの実験系ではボイデンチャンバー法、細胞動態解析技術等を用いることができる。簡単には、ボイデンチャンバー法は、細胞走化性を定量する有効な方法であり、ボイデンチャンバー内に別のコンパートメントとしてインサートがあり、このインサートの底面は均一なサイズ(例えば、約8μm)の微細孔を多数有するフィルターが装着されている。そのフィルター上に細胞を含む細胞培養液を添加し、インサートの下部に遊走因子を含む培養液を添加することによって、フィルターの微細孔に生じる遊走因子の濃度勾配に沿って細胞がフィルターを潜り抜けて下方に移動することを利用したものである(図2)(例えば、Boyden,S.,J.Exp.Med.,Vol.115,p.453-466(1962)を参照されたい)。このように、フィルターを通過した細胞数をカウントすることによって走化性の程度を定量的に測定することができる。本発明では、遊走因子の候補物質をインサートの下側に添加し、上側にMuse細胞を添加後、Muse細胞の移動数をカウントすることによって、添加した候補物質が遊走因子として作用し得るかを評価することができる。
本発明は、Muse細胞の遊走能活性を亢進し、Muse細胞を損傷部位に誘導する遊走因子を有効成分として含む医薬組成物を提供する。本発明の医薬組成物に使用される「遊走因子」とは、例えば、Muse細胞の細胞表面上に発現している受容体に結合し、その結合を介して、細胞の遊走に関与するシグナル伝達系が活性した結果、細胞を遊走因子に指向されて遊走させる物質を意味する。また、本発明において使用するとき、用語「損傷部位」とは、生体内における各種の臓器、器官、及び組織において、外傷、炎症、疾患、虚血、壊死、腫瘍形成、又は加齢等を原因とした各種細胞及び組織との変性又は脱落によって失われた特定の部位を意味する。本発明によれば、Muse細胞を損傷部位に集積させるためには、遊走因子を医薬として許容される担体、及び/又は希釈剤を配合した医薬組成物として使用してもよく、又は遊走因子を単独で用いてもよい。ここで、本発明の医薬組成物に含有する遊走因子としては、Muse細胞を損傷部位に誘導する能力を有する物質(例えば、タンパク質、ペプチド、脂質、化合物等)であれば特に限定されない。より好ましくは、遊走因子は、スフィンゴシン-1-リン酸(S1P)、スフィンゴシン-1-リン酸誘導体、並びにスフィンゴシン-1-リン酸受容体のアゴニストである。ここで、「スフィンゴシン-1-リン酸(S1P)」とは、下記式:
Muse細胞を損傷部位に誘導する遊走因子の候補物質を選出するために、首都大学東京の磯辺教授らのグループによって開発されたプロテオーム解析法を用いた(田岡ら(2004)、上述参照)。この方法は、タンパク質混合物のプロテアーゼ消化で生じる複雑なペプチド混合物を分析することにより、もとの試料に含まれるタンパク質を多量に同定する方法であり、「ショットガン法」とも呼ばれる。この方法を実施するための自動化システムは、イオン交換LC、分離用の逆相LC、及び脱塩システムを連結した複合型LCシステムと、ハイブリッド型質量分析計、データ解析システムから構成されている。複合型LCシステムでは、特に、分離様式の異なる2種類のLC(イオン交換系及び逆相系)を組み合わせることを特徴とし、システム全体の分離能は、それぞれの分離法がもつ分離能の積として得られるため、非常に多数のタンパク質又はペプチドを分離することができる。次に、生体試料を質量に依存して高解像度で分離し、さらに質量情報を与えるMSを利用することにより、続く配列情報のデータベース検索によりタンパク質又はペプチドを同定することができる。例えば、細胞又は組織の粗抽出液をトリプシン消化して得られた非常に複雑なペプチド混合物から、1回の分析で訳10,000~15,000のMS/MSスペクトルを取得し、ほぼ1,000種類のタンパク質に由来する2,000~3,000種類のペプチドを同定することができる。本実施例においては、上記の磯辺らの自動化システムを用いることにより、非Muse細胞と比較して、Muse細胞に特異的に発現しているタンパク質を特定した。
(1)ヒトMuse細胞の調製
ヒトMuse細胞の調製は、国際公開第WO2011/007900号パンフレットに記載された方法に従って行った。より具体的には、ヒト骨髄液から接着性を有する間葉系細胞を培養し、増殖を経て、レンチウイルス-GFPを細胞に導入した。GFPで標識されたMuse細胞又はMuse細胞を含む細胞集団をGFPとSSEA-3の二重の陽性細胞としてFACSにて分離した。また、非Muse細胞は、上記間葉系細胞のうち、SSEA-3陰性であるGFP陽性の細胞群であり、対照として用いた。その後、リン酸緩衝生理食塩水又は培養液を用いて、所定濃度に調整し、以下のボイデンチャンバー法及び細胞動態解析技術に使用した。なお、骨髄間葉系細胞などの間葉系細胞を培養して得たものをMuse細胞の母集団として用いる場合、Wakaoら(2011、上述)によって報告されているように、SSEA-3陽性細胞は全て、CD105陽性細胞であることが分かっている。
遊走因子によるMuse細胞の遊走を定量的に測定するためにボイデンチャンバー法を用いた。使用したボイデンチャンバーは、Milliporeから市販されているQCM Chemotaxis Cell Migration Assay Kit(QCM 24 Well Colorimetric Cell Migration Assay)を使用した。このボイデンチャンバーは、チャンバー内部に、8μmの均一な微細孔を有するフィルターを底部に有するインサートを含む。インサートのフィルター上部にMuse細胞又は非Muse細胞を含む培養液を添加し、インサートの下部に遊走因子を含む培養液を添加し、18時間培養後、フィルターの微細孔を通過した細胞数をカウントする(図2参照)。この方法を用いれば、実施例1で得られた、遊走因子の候補をそれぞれ試験することにより、Muse細胞に対する遊走因子を特定することができる。
細胞動態解析技術は、ECI社が開発した細胞遊走能解析法である(Nitta, et al., Journal of Immunological method;320,155-163(2007)を参照されたい)。この解析法に使用される装置では、最新の微細加工技術を駆使して作成したシリコンウエハーチップを用いて、一定の走化性因子の濃度勾配を形成させ、その勾配依存的な細胞の水平方向への遊走活性測定が可能なシステムを用いる(図4)。このシステムから結果として得られる画像を解析することによって、方向性(例えば、Muse細胞が遊走因子高濃度側に対してどれだけ方向的に進んだか)を定量化することができる(図5)。
マウスを実験モデルとして、生体内において遊走因子によってMuse細胞が集積されるかどうかを以下のように行った(図7参照)。使用したマウスは、ヒト細胞を拒絶しない免疫不全であるSCIDマウス(雄性7週齢)を日本SLC株式会社又は日本チャールス・リバー株式会社から購入した。遊走因子としてS1Pを用いた。予めS1P溶液(500nM又は1,000nM)を染み込ませた、大きさ0.5cm×0.5cmの生分解性ハイドロゲル(MedGel(登録商標)製)をマウスの背中の任意部位に移植した。その後、実施例1で調製したGFP標識されたヒトMuse細胞をマウスの尾静脈から注入した。2日後、移植した部位からハイドロゲル周辺の組織を取り出し、GFPの抗体を用いてGFP標識を検出し、GFP陽性のMuse細胞をレーザー顕微鏡にてカウントした。
